JPS59425Y2 - floor beam - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a floor beam that forms the boundary between a downstairs and an upstairs floor.

A floor in an architectural structure such as a prefabricated house is constructed as described below.

That is, the mounting hardware is fixed to a floor beam spanning the pillars, and the floor panel is attached to this.

Therefore, mounting hardware is always required and installation is time-consuming, and the floor panel tends to be misaligned with respect to the pillars or floor beams, making it difficult for the land to protrude.

The present invention was developed in view of the above circumstances, and its purpose is to provide a floor beam that facilitates the installation of floor panels and ceiling panels and improves workability and assembly accuracy. It is something.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows a part of the floor beam, and 1 and 1 are the upper and lower floor beam materials.

This floor beam material 1 is formed by bending a metal plate, and the central part has a substantially U-shaped cross section, and both end edges have flanges 1a and 1a along the longitudinal direction. It is provided integrally and has a generally hat-shaped cross section.

The floor beam materials 1, 1 formed in this way each have a groove 1.
b and lb are vertically opposed to each other, and the lattice bar 2...
... are connected.

The lattice bar 2 is formed by bending a metal plate into a substantially U-shaped cross section, is inclined along the longitudinal direction of the floor beam material 1, and has both ends fitted into the grooves 1b, lb. and welded.

Therefore, the lattice bar 2... is the floor beam material 1,1.
It will meander in a 99-fold pattern between the two.

A plurality of sets of floor beams constructed in this manner are prepared and used, for example, as floor beams forming the boundary between the first and second floors of a prefabricated house.

That is, as shown in Fig. 2, floor beams A are fixed to pillars (not shown) at a predetermined interval, and a floor panel B is placed between the opposing upper floor beams 1, 1. Install.

Both sides of the floor panel B are placed on top of each other's collar pieces 1a and 1a, and may be fixed to each other by some means.

In addition, a ceiling panel C is attached to the lower floor beam members 1, 1 which face each other.

Both sides of the ceiling panel C are engaged with the lower surfaces of each other's flange pieces 1a and 1a, and may be fixed to each other by any means.

The floor and ceiling are constructed in this way, each with easy access.

Further, although the lattice bar 2 is formed from a metal plate having a substantially U-shaped cross section, it is not limited to this, and may be replaced with a round bar made of a metal material, for example.

As explained above, according to the present invention, a pair of floor beams, each having a collar integrally provided on both ends of a substantially U-shaped cross section and having grooves facing each other in the vertical direction, are formed using a lattice bar. Because they are connected, they have greater strength, and when attaching the floor and ceiling panels, you only need to use the flanges, which makes the work much easier and allows for more accurate assembly, and eliminates the need for conventional mounting hardware. It has the effect of reducing costs and being ideal as a floor beam.

Claims (1)

[Scope of utility model registration request] In a structure that is used as a boundary between a downstairs and an upper floor and has floor beams placed opposite each other at the upper and lower portions, the upper and lower floor beams are made of metal and are bent to have a roughly U-shaped cross section. A flange is integrally provided on both edges of the surface, and the opening surfaces of the grooves of the upper and lower floor beams are vertically opposed to each other, and both ends of a metal lattice bar are fixed to these grooves, so that the openings of the grooves of the upper and lower floor beam members are fixed to each other. A floor beam characterized by being made by connecting floor beam materials.
